Astrobiologists claim meteorite carried space algae
'Listening' to black holes form with gravity waves
New technology that breaks the quantum measurement barrier has been developed to detect the gravity waves first predicted by Einstein in 1916.
Looking at quantum gravity in a mirror
Einstein's theory of gravity and quantum physics are expected to merge at the Planck-scale of extremely high energies and on very short distances. At this scale, new phenomena could arise. However, the Planck-scale ...
Researchers suggest gas cloud could reveal black holes near center of Milky Way galaxy
Does antimatter weigh more than matter? Lab experiment to find out the answer
Does antimatter behave differently in gravity than matter? Physicists at the University of California, Riverside have set out to determine the answer. Should they find it, it could explain why the universe ...
Did Andromeda crash into the Milky Way 10 billion years ago?
(Phys.org) —For many years scientists have believed that our Galaxy, the Milky Way, is set to crash into its larger neighbour, the Andromeda Galaxy, in about 3 billion years' time and that this will be ...
Researchers measure Brazil nut effect in reduced gravity
Physicists devise means for observing single atom interference over coherence length
Team solves the origin of the Moon's 'mascons' mystery
A mystery of the moon that imperiled astronauts and spacecraft on lunar missions has been solved by a Purdue University-led team of scientists as part of NASA's GRAIL mission.
Researchers find winds on Uranus and Neptune confined to thin atmosphere layer
A brighter method to determine surface gravity of distant stars
Astronomers have found a clever new way to slice and dice the flickering light from a distant star in a way that reveals the strength of gravity at its surface.
Earth’s other moons
(PhysOrg.com) -- Earth usually has more than one moon, according to a team of astronomers from the University of Helsinki, the Paris Observatory and the University of Hawaii at Manoa.
Light from galaxy clusters confirms theory of relativity
All observations in astronomy are based on light emitted from stars and galaxies and, according to the general theory of relativity, the light will be affected by gravity. At the same time all interpretations ...
